Fluid dispense and fluid surface verification system and method

摘要

A method of detecting fluid flow through a conduit due to the operation of a fluid pump to determine if a predetermined amount of a fluid was moved through the conduit by operation of the pump comprising: measuring pressure within the conduit; determining a duration of an increase in pressure within the conduit associated with fluid movement through the conduit due to the operation of the pump; and comparing the determined duration of increased pressure to a duration or a range of durations that would be expected if the predetermined amount of fluid were moved through the conduit.
